Wool is a organic material and is very sensitive to high temperatures. It has the ability to clean itself so the best way to take care of your knitwear is to airing it. All of our knitwear is maschinewashable but it has to be washed on a seperate wool program on max. 30C. It is important only to use soap which is made for wool products and also remember not to use high centrigution, which can damage the fibres in the wool.
